Perfumed with fresh thyme sprigs and served with a piquant mustard-sour cream dressing, these baked sweet potatoes hit all the right notes – sweet and velvet fleshed, pleasantly tangy, and herbal. You can stir the sauce together several hours or even the day before, and leftovers will keep in the fridge for up to 3 days. Other herbs – rosemary, tarragon, sage – can fill in for thyme. (To make this recipe vegan, try substituting coconut yogurt or 1/4 cup olive oil for the sour cream.)
